Let's be honest, the real reason is that cyclists are frustrating to drivers merely by being cyclists. They're slow so they force the driver to either try to overtake or slow down everyone behind them and most people when driving will feel a pressure not to slow down the journeys of others behind them. So long as cyclists and drivers share the same roads it will always exist, some drivers will just be better about it…
The funny thing though is that, in most urban settings, this is completely untrue. Cyclists actually speed things up by creating less traffic. Every cyclist on the road means less cars on the road. And the speed of traffic is not determined by the speed of the cars, which most drivers seem to believe for some reason. In a city, the speed of traffic is entirely determined by the stop signals. There is a fixed time it…

While that part is certainly more true than not, the implications of fewer cars but several bottlenecks added to the traffic system is far from certain and likely relies on so many other factors than just the number of bikes on the road.
